Wavefront parallelism is effective for parallel video encoding thanks to its merits of low latency, no quality.loss and high degree of parallelism. In traditional video encoders, macroblock row wavefront (MRW).parallelism was widely adopted. However the performance of MRW is limited by workload unbalance.and computing resource unbalance among multiple work threads. This paper proposes a new dynamic.macroblock wavefront (DMW) parallelism to alleviate the limitations of MRW. In DMW, the available.
